Hey yall
I have a 2002 sti prodrive and it's come with 10j rotas with no arch modification so as you can imaging it's a bit crazy right now , I don't want to chop and change the car atall I just want to sell the wheels that are on it now and buy some new ones (fresh start)
My question is what's the biggest widest wheels I can have with no arch modification
I've been looking at 18× 8.5's but don't know my limits with offset
Cheers in advance guys

 

Would 18 × 8.5 et38 fit ? Anybody ?

Bump

 

Anyone ?

 

I've got this size wheel on my 2002 Prodrive fitted with 225 x 40 x 18 Yokohama tyres. The car is approx 30mm lower all round and these fit under the arches without rubbing.

 

Brilliant answer cheers mate
